Compact side inlet and outlet exhaust aftertreatment system

Abstract

An exhaust aftertreatment assembly and method of manufacturing and operating an exhaust aftertreatment assembly. An exhaust aftertreatment assembly includes an aftertreatment housing and an inlet conduit coupled to the aftertreatment housing at an inlet port so as to transfer exhaust gas into the aftertreatment housing. An inlet chamber is positioned in the aftertreatment housing. The inlet chamber is fluidly coupled to the inlet port of the aftertreatment housing to receive the exhaust gas from the inlet conduit.

         29 . A method of servicing an aftertreatment system mounted on a vehicle, the aftertreatment system comprising an aftertreatment housing having a longitudinal flow axis, an inlet port and an inlet chamber positioned orthogonally to the longitudinal flow axis, and an outlet port and an outlet chamber also positioned orthogonally to the longitudinal flow axis, the method comprising:
 shutting off the vehicle;   removing at least one used aftertreatment component from an internal volume defined by the aftertreatment housing without removing the aftertreatment system from the vehicle; and   positioning a serviced or new aftertreatment component within the internal volume of the aftertreatment housing.   
     
     
         30 . The method of  claim 29 , wherein the used aftertreatment component includes a particulate filter. 
     
     
         31 . The method of  claim 30 , wherein the particulate filter is positioned within a first portion of the internal volume defined by the aftertreatment housing, wherein the at least one aftertreatment component also includes a selective catalytic reduction component positioned within a second portion of the internal volume of the aftertreatment housing, the second portion downstream of the first portion, and wherein the method further comprises:
 removing the selective catalytic reduction component from the second portion of the internal volume of the aftertreatment housing without removing the aftertreatment system from the vehicle; and   positioning a serviced or new selective catalytic reduction component within the second portion of the internal volume of the aftertreatment housing.   
     
     
         32 . The method of  claim 30 , wherein the particulate filter is a serviceable diesel particulate filter section configured to be separately removed from the exhaust aftertreatment system.
